SHIPPER-RELEASING MECHANISM FOR ELECTRICALLY-CONTROL-LED WARP STOP MECHANISM.

To all whom it may concern:

Be it known that I, CHARLES D. LANNING, a citizen of the United States of America, residing at Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented certain Improvements in Shipper- Releasing Mechanism for Electrically-Controlled Warp Stop Mechanism, of which the following is a specification.

The invention relates to mechanism for releasing the shipper-lever in electrically controlled warp-stop-mechanism in looms, without the intervention of any going part of the loom, and consists of a magnet in the circuit which includes the drop-bar terminals, and mechanism connected with the armature of the magnet, which mechanism acts directly to release the shipper-lever when the circuit is closed by the contact of a drop-bar with terminals of opposite polarity; and the invention further consists in a cut-out for the drop-bar terminals, which is operated by the magnet when a drop-bar closes the circuit, and by the same operation closes a short circuit through the magnet and electrical generator in order to give increased energy to the magnet to operate the shipper-lever. solenoid magnet is found preferable for the purpose as it gives greater range of motion and is the form of magnet illustrated in the accompanying drawings, and wherein the movable core is intended to be included in the general term armature.

In the drawings, Figure 1 is a side elevation of a solenoid magnet, and the combined cut-out for the drop-bar circuit and switch for the short circuit; Fig. 2 is an elevation of the end of a loom-frame, showing the shipper-lever, the magnet, the mechanism operated thereby to release the shipper, and the electric circuit; Fig. 3 is an elevation of the drop-bars and their contact terminals, the lease-rods and warp-threads which normally support the drop-bars; the lease-rods and terminals are in section; Fig. 4 is a diagrammatic View of the improvements, with the circuits, the drop-bars, their electric terminals, the magnet, shipper-lever and mechanism to release it.

Referring by designating characters to the parts illustrated in the drawings, A is the loom-frame, S the shipper-lever, M the magnet, preferably mounted upon the loom frame and here shown as a solenoid andpro- Specification of Letters Patent.

vided with a core m; e a lever vpivoted to the frame A at e. The long end of this lever is pivoted to the outer end of the core m, and the short end thereof is so located in reference to the shipper-lever S that when the core m is drawn into its magnetic coil, the swing of the lever Z will push the shipperfrom its retaining notch.

C is the circuit wire, extending from the generator G to the magnet M, the terminals a t and the drop-bars d which are normally supported out of contact with the terminals by the warp-threads w.

B is the cut-out, and short circuit switch, which makes contact with terminals 19 b and which is attached to and operated by the armature E pivoted at e. The armature E is controlled by the stationary part m of the core of the magnet M.

In Fig. 4:, C indicates the circuit closed by the drop-bars, and C indicates the circuit closed by the switch B.

F (Fig. 4) is a spring with which the shipper S makes contact to close the circuit when in its retaining notch, and with which it breaks contact when released from the notch. In Fig. 2, H is the belt shifting or clutch releasing lever operated by the shipper S when it is released.

The operation of these improvements will be readily understood by reference to Fig. 4. When a warp-thread breaks or becomes abnormally slack, a drop-bar 0? falls and closes the circuit C by making contact with the two terminals 25 If; this energizes the magnet M and causes the armature E to be drawn to the core m thereby withdrawing the switch arm B from the contact 5 and transferring it to the contact 5 thus cutting out the circuit C and switching in the short circuit C, by which a stronger current will pass through the coils of the magnet M and draw in the core 1%, which will carry the long end of the lever Z with it and cause the short end of the lever Z to release the shipper S from its retaining notch. By positively cutting out the circuit C and substituting the short circuit C, I prevent such loss or dissemination of current as would occur were merely a shunt circuit provided, since in practice the current would not be absolutely confined to such shunt circuit, and hence the current available in such case to operate the armature would be correspondingly weakened. When the shipper is released it will break the circuit at the spring F and the switch arm B will be returned to its normal position by a spring I.

Attempts have been made to release the shipper-lever by employing the shipper as the armature of the magnet, but this has proved impracticable, because the same force that is employed to release the shipper-lever tends to hold it; and this disadvantage is intensified because of the strength of current required in a magnet designed to work in such a direct manner.
